从对象到数组在doctrine2中

Question

I'm using Doctrine 2 ORM to map my SQL table into objects. Is there a support method like asArray which converts my objects into an array?

Answer 1

You can simply use the getArrayResult method that is mentioned here inside the Doctrine 2 documentation chapter 14.7.4.2. Array Hydration :

$array = $query->getArrayResult();

It is a short notation for, and does exactly the same as, this answer that that @Joucks is pointing to in his comment :

$array = $query->getResult(Query::HYDRATE_ARRAY);

But you don't necessarily have to look at specific Doctrine ORM solutions for such serializing functionality. You could also look at solutions that come with the PHP framework that you are using.

Zend-Framework

For example if you use Zend-Framework you could implement the ArraySerializableInterface inside the objects that you want to be able to serialize to an array.

This interface includes an getArrayCopy method that should return the object serialized to an array.

You can read more about ArraySerializable inside the Zend-Framework 2 Zend\\Stdlib documentation

Symfony

Symfony ships with this Serializer component .

For other frameworks I expect they are shipped with similar interfaces/solutions.
